Oil \( + NaO{H_{(aq)}}\xrightarrow{\Delta }\) Glycerol + SoapAbove reaction is called
1 Saponification
2 Esterification
3 Hydrogenation
4 None of these
Explanation:
Saponification is a process that involves the conversion of fat, oil, or lipid into soap and alcohol by the action of heat in the presence of aqueous alkali. Esterification is the process of combining an organic acid \((RCOOH)\) with an alcohol \((ROH)\) to form an ester \((RCOOR)\) and water. Hydrogenation is a chemical reaction between molecular hydrogen \(\left( H _2\right)\) and another compound or element, usually in the presence of a catalyst such as nickel, palladium, or platinum. Hence, the given reaction is a saponification reaction.
